Hello. I noticed problems with ASUS ZENPHONE 2 and recording videos. Not so much the loss of frames but the recording of low quality, as if it always recorded with a few bitrates even if you imposed the video at the highest quality.

Do you have other phone? Iphone is the best one. WiFi repeater also will help to reduce frames skip.

Sorry that the bit rate would keep unchanged if you switch to high-quality option. To get a better view, please go to setting - more setting - bit rate and set it to 4Mb and fly in an open area with less interference.
